RiRi (SweeTeez) × Sakai Erika × Lily Chow × Moon Sunwoo release the “FLASH!!” music video

The music video for “FLASH!!”, a unit track by four MYBLIN9 AI artists, was released on the MYBLIN9 official YouTube channel on October 6, 2026. The unit brings together SweeTeez member RIRI (PRODUCE 9 #96), Harajuku solo artist Sakai Erika (#32), Lily Chow (#31) and Moon Sunwoo (#47).

“FLASH!!” mixes Heisei-era gyaru style, para-para dance and Eurobeat. The four’s stage begins the moment headlights flash on a midnight highway, and with every FLASH the world switches — a mirror-ball megaplex, a neon cruise, a kaleidoscope, a sky-high disco, the Shibuya scramble crossing and a frozen glitter universe. There is always one empty spot at the right end of their line-up: number five is you.

The song was written and composed by JIHO, mixed by $hark and mastered at MasteringOne.com, and the music video was directed by Derek Kim.
